Title: Improvements relating to means for discharging or delivering material containing dust or like finely divided material
IPC: F23J1/00
Filed: 1949-07-15
Abstract: 669,927. Shoots. BALFOUR, BEATTY & CO., Ltd., and ALEXANDER, W. M. July 13, 1950. [July 15, 1949] No. 18753/49. Class 78 (i). A telescopic shoot for delivering ash and other finely divided materials to a receptacle is arranged so that when extended the delivery end will be closed by engagement with a surface of the receptacle and is connected to an exhauster so that dust laden air is withdrawn from it and from around its delivery end as the latter is raised to deposit the material. Water spraying nozzles may be provided within the shoot to moisten the material. The shoot comprises a fixed inner member 13, Fig. 3, and an outer member 14 which is suspended by cables 17 attached to winding drums 20 on a shaft 21. This shaft is connected by worm gearing to a spindle which is connected by chain-and-sprocket gearing to a chain wheel within reach of the operator. The shoot is separated from the hopper 10 by a draw plate valve which is operated by an endless chain passing around another chain wheel near the operator. Sprockets 31, Fig. 4, and 32, Fig. 6, on the shaft 21 are connected by chains 33, 34 to the spindle 36 of a vacuum control valve and the spindle 47 of a water spray control valve, respectively. The vacuum control valve (not shown) is in a pipe connected to the upper part of the member 13. The sprocket 31 is connected to the shaft 21 through a free-wheel device and is driven only when the shaft is rotated in the direction to raise the member 14. Dogs 39 on a sheave 37 fast on the spindle 36 are adapted to be engaged by a pair of projections 40 on the chain 33. The chain is of such a length that it makes a complete circuit during the upward movement of the part 14. A sheave 49 fast on the spindle 47 has radial dogs 50, 51, 52 on each face, the dogs 50 projecting farther than the other dogs. The chain 34 has two pairs of lateral projections 53, 54 so arranged that the projections 53 engage between the dogs 50, 51 and the projection 54 between the dogs 50, 52. In Fig. 6, the sheave 49 is shown in the position in which the water valve is closed. During lowering of the member 14 the sheaves rotate in the direction of the arrows and the projections 54 engage the dogs 52 to turn the sheave to bring the dogs 50 into the path of the projections 53. The engagement of these parts causes the opening of the valve. When the member 14 is raised, the sheave 49 is returned to its original position and the valve closed. In a modification, the vacuum control valve and the water valve are actuated by rack-and-pinion mechanism, the racks being mounted on the member 14.

Title: Improved method of distilling large quantities of liquid
IPC: H04B14/02
Filed: 1936-07-06
Abstract: <PICT:0482883/III/1> A process of high-vacuum short-path distillation for relatively non-volatile organic compounds such as animal and vegetable oils, hormones, sterols, sterol derivatives, enzymes, unsaturated glycerides &c. consists in disposing the distilland on a distilling surface in a thinner layer than is possible by gravity, e.g. by centrifugal force.  One form of apparatus for the purpose comprises a high-vacuum vessel 1 containing rotating plates 22, 24, 26, 28, of which the plate 28 dips into a heating liquid 32 and distributes it on the inner surfaces of the plates 24, 26, while the distilland is fed on to the plate 22 by a pipe 37 and is centrifugally projected into a gutter 6, from which it flows by a pipe 11 on to the plate 24, which projects it into gutter 8, and during its flow over the plate 24, the distillate is condensed on the underside of the plate 22 and is flung on to a collar 30 from which it passes into gutter 7 provided with a draw-off pipe 9.  In another form, plate 22 is fixed to plate 24 by welded spacers, and the distilland is fed on to plate 24.  In another form, three horizontal rotating discs are arranged in the planes of three gutters in the wall of the chamber the top and bottom discs extending into the gutters, while the middle one is of smaller size and receives on its upper surface the distilland from a heated tube.  In another form, a rotating drum is heated by a body of liquid in its lower part, and is arranged inside two concentric cylinders welded together at the edges to form an annular space through which cooling fluid is circulated. The distilland is spread on the drum by a small roller, and the distillate is condensed on the inner surface of the cooling jacket. In another form, two vertical concentric cones with their smaller ends at the bottom are used, the outer one being rotated and heated on its outer surface, while the inner is stationary and cool.  The distilland is fed on to the lower inner surface of the rotating cone, and the distillate is condensed on the cooled cone. British Specifications 482,880, and 482,882, and U.S.A. Specifications 27,503, 37,258, 1,766,699, and 1,942,858 are referred to.

Title: Improvements in or relating to programme control devices
IPC: G06F3/08
Filed: 1961-05-24
Abstract: 974, 813. Mechanical calculating apparatus. ADDO A.B. May 24, 1961 [May 27, 1960], No. 18808/61. Heading G4B. The output of a calculating machine is punched order-by-order in eight-hole paper tape under control of a program punched card, rows of which are examined sequentially and compared with the setting of operation keys of the keyboard to control the transfer to tape. As shown the calculating machine has eleven decimal orders, the contents of which are represented by the position of sliding contacts 209 on digit bars 211. These bars are connected to a diode coding matrix 318 so that any energized slider will cause the operation of punch electromagnets 306 &c. and also over transistor 325 energize tape advance mechanism. This is cam-coupled to switches 369, 370 which operate a stepping switch S with sliders S-A, B and C to advance to the next decimal order for scanning the calculator digits in sequence. There are corresponding digit switches IK I-XI controlled by eleven columnar positions on the program card so that the punch-out of digits can be made selective, e.g. a row of the card can be punched to order the punch-out of digits I-IV only, the stepping switch being advanced without energization of some of the sliders 209. Other columns on the punched card (it has 24) are used to control "conditional punch-out", in which the orders in them are compared with the setting of operation keys controlling slider 404, so that e.g. when the punch-out of a total is ordered such punch-out can be delayed until the summing operation in the calculating machine is complete. Suppression of zeros to the left of the most significant digit is possible, and various other conditions affecting the punching of the tape are discussed in detail.

Title: Improvements in the manufacture of enamelled wire
IPC: C23D5/02
Filed: 1944-10-03
Abstract: 583,321. Coating wire. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and HOLMES, W. T. Oct. 3, 1944, No. 18916. [Class 140] [Also in Group XXII] In a method of producing enamelled wire by a continuous process, the bare wire of greater diameter than its final size is drawn through a die to effect a small reduction in its cross section and produce a fresh clean surface, the lubricant is removed and the wire is passed into the enamelling apparatus, the power for the drawing operation being applied to the wire immediately before it enters the enamelling machine. A group of ten wires 1 from bobbins 2 are taken over a multi-grooved pulley 4, beneath a roller 23 dipping into a lubricant bath 22, through a group of drawing dies 24 and then by way of a pulley 26, felt wipers 27 and a capstan 8 to a bath 28 of spirit for removing the final traces of lubricant. The bath 28 is contained within the enamelling tank 11 and after leaving the spirit bath the wire travels upwardly through a drying oven, down into the enamelling tank and up again into the oven. A number of coats of enamel may be applied before the finished wires 7 pass over pulleys 15, 16, 18 and 19 to the take-up bobbins 6. The pulleys 15 and 16 are driven through gearing from a motor 17 and the capstan 8 is driven by a belt 21 from the pulleys 15 and 16. With wires within the range 32 to 25 S.W.G. the dies are preferably fed with bare copper wire of the next larger S.W.G. size to the size required in the finished article. The speed of the drawing is considerably less than that ordinarily employed in drawing operations and may vary from 5 to 100 feet per minute.
